Beyond that, 2.5" true duals w/a H-pipe or X- crossover would be a decent set-up. Summit has a aluminized universal kit as well as a SS version.

Thank you sir. It funny you post this and i have been doing some research into how to pick header size and length, x vs h pipe and full size of exhaust. I came to the conclusion you show also. The negative with the larger headers are the issues with plugs and burning wires, that is basically the only neg. that i found. I am going with the 2.5" exhaust, even looking at kit Captainfab posted.
Thanks again Scoti.
